Cinquecento/Seicento 1.4 engine into a cinq (useful info and links)

The coolant temperature sensor to the side of the inlet manifold has a different connection to that of the punto loom. Easiest away around it is to fit your cinquecento one.


Fitting a breather filter?
If you wish to fit a breather filter, it saves you joining the hose to the induction. MOT stations can now add this to the emissions depending how awkward they want to be as it is another exit for gasses.
A breather can be fitted directly to the top of the flame trap as the flame trap stays in place when the hose is remove.


Connecting up the fuel pressure regulator
The supply is the one on the right and the second return is the left one. The second return will already be blocked off if following this guide.
If using the replica FPR it comes with a handy bracket. I bent this into a flat bracket rather than the right angled bracket and mounted it here, however you can mount it werever you see space really.



Since writing this guide i have altered the position of this FPR as it is too close to the exhaust manifold and risks getting vapour lock. It is now where the heater box is/was

The small connector is a vacuum pipe and needs to be joined to the inlet manifold. If using the stilo manifold there is spare connection to the rear nearside of the inlet manifold that was used for the evaporator that has now been removed. If you are keeping the charcoal cannister set-up you can put a Hose T connector onto this pipe.
I found 5mm silicone hosing is a perfect fit for both the FPR and inlet vacuum connections

The other connection to the inlet manifold can now be either blocked off or used as the vacuum for the FPR as it is slightly closer to one of the mounting possibilities next to the headlight.

Relocating the coolant tank (if using stilo inlet manifold)
You will not have this problem if using the punto inlet, but still worth considering moving as it looks soo much tidier.
If using a stilo inlet manifold the coolant tank will contact the edge of the inlet manifold where the MAP sensor is positioned.
This means you can either mess around trying to make it fit here or move it to where the battery is and put the battery in the rear.



For moving the battery to the rear of the car, this link is extremely useful:

To attach the coolant tank i used the original mounting bracket. Simply cut it into a thin strip. Quite simple as shown:



This means that the holes are already the correct size for the bolts and you dont need to buy metal sheeting or attempt to cut it smoothly.

The radiator and fan can now be put back in.

The brake servo hose can now be joined to the inlet manifold.

The clutch cable can be re-attached along with the 2 selectors for the gearbox.

The driveshafts can be put back in place with the new boots, grease and hub nuts.

The throttle body can be attached if it hasnt already. If using the stilo inlet a spacer will need to be made. The induction can now be attached.
